Raman spectroscopy is a technique that has made its way into a great deal of new fields and shown a lot of promise in a vast number of scientific questions. Understanding the TechnologyHigh-precision Raman measuring tools gather data about objects at the micron scope. Typically, a coherent light is shined upon the subject material. The laser beam will refract in a unique pattern depending on the material it lands on. Observing the scatter makes it possible to identify the substance or substances being looked at, their degree of concentration, and other traits. The technique -- which is actually a series of slightly varying measuring strategies -- is so called because of the Raman effect, which is where electromagnetic waves collide with a molecule and interact with its bonds. In this case, a monochromatic wave of light is employed, making it easier to interpret the outcome. ApplicationsChemistry is the field in which TouchRaman spectroscopy is most often applied because it collects its data from reacting to chemical bonds. However, its applicability is wide-ranging. Pharmaceutical researchers use specialized instruments such as TouchRaman probes to measure active ingredients in medications, and what form those ingredients take at the molecular level. TouchRaman tools such as these can also be key in physics experiments to determine the crystalline state of substances, as well as measure their temperature. Some TouchRaman probes can even collect data regarding corrosive substances that would ordinarily destroy the measuring tool. Spatially Offset Raman SpectroscopyAnother type of Raman spectroscopy, referred to as "spatially offset Raman spectroscopy," is able to ignore surface layers and can be applied to, for instance, positively identify counterfeit medications without disturbing their containing packages. They can also be utilized to track changes in biological cells, like an ultrasound. Experiments are under way to see whether different TouchRaman and similar devices can be utilized to find explosive substances from a distance, and even to discern whether individual living cells are cancerous, potentially making surgery considerably safer and more precise, boosting favorable prognoses considerably. MicrospectroscopyRaman spectroscopy can be utilized to examine minerals, cells, and forensics evidence on a microscopic level. Lab techs can even use it to measure the level of cholesterol or other substances in foodstuffs. CustomizationWhile manufacturers such as raman analysis sometimes sell ready-made TouchRaman and similar instruments to government, academic and pharmaceutical organizations, those manufacturers can also specialize and build machinery optimally suited to the measurement and observation needs of the individual order.
